mymesh.rays.RayBoundaryIntersection

mymesh.rays.RayBoundaryIntersection(pt, ray, NodeCoords, BoundaryConn, eps=0)

Identify intersections between a ray and a boundary mesh of line elements. This is generally intended for 2D boundary meshes, though it will work in 3D as well.

Parameters:

• pt (array_like) – 3D point coordinate (shape = (3,))

• ray (array_like) – 3D vector (shape = (3,))

• NodeCoords (array_like) – nx3 list of node coordinates

• BoundaryConn (array_like) – List of line element connectivities. This should have shape = (n,2)

• eps (float, optional) – Small tolerance parameter, by default 1e-14

Returns:

• intersections (np.ndarray) – Indices of line segment elements that are intersected by ray.

• distances (np.ndarray) – Distances between the point and the intersection points.

• intersectionPts (np.ndarray) – Coordinates of intersection points for each intersection.
